LONG BEACH — A Long Beach police officer already arrested for sexual offenses involving a minor is scheduled to be arraigned Friday on dozens more criminal counts for allegedly engaging in lewd acts with multiple underage girls dating back to 2008.

A total of 39 criminal counts, both felony and misdemeanor, were filed against Noe Yanez by the Los Angeles County District Attorney's Office on Monday, said Jane Robison, DA spokeswoman.

A warrant for Yanez's arrest was issued that same day, Robison said.

Yanez was picked up by Long Beach police Wednesday and booked into the Men's Central Jail in Downtown Los Angeles that afternoon, where he was being held Thursday in lieu of $950,000 bail, according to authorities.

According to the criminal complaint, Yanez engaged in sex-related acts with 13 girls, all of whom were under the age of 18, between January 2008 and April of this year. The complaint also charges Yanez had unlawful sexual intercourse, engaged in oral copulation, committed penetration with a foreign object and provided alcohol to one victim.

Seven counts of false imprisonment by violence were filed, including one girl who was allegedly held against her will last Christmas Eve.

The complaint includes dozens of counts of misdemeanor child molestation, felony contact with a minor for a sexual offense and meeting a minor for lewd purposes.

Yanez, a nine-year veteran of the force, was assigned to the Patrol Division at the time of the alleged crimes. Police and prosecutors haven't said if he met his victims through his job, citing the sensitive nature of the investigation.

Yanez was first arrested and booked on April 19 for possession of child pornography following an investigation into his alleged inappropriate contact with a girl, which, according to police, began with text messages and the solicitation of inappropriate photographs.

The LBPD launched its investigation after the girl reported the alleged conduct to a school resource officer in March. School resource officers are only assigned at high schools, authorities explained.

Yanez was suspended without pay following his initial arrest and remains on suspension pending the outcome of the internal and criminal investigations, police officials said.

He posted bond April 20, following his first arrest, and had been scheduled to be arraigned on that charge Friday at the Long Beach Superior Court.

However, due to the additional victims and the serious nature of the allegations, Yanez's case is now being handled by the DA's Public Integrity Division. He is scheduled to be arraigned on the new charge Friday at the Downtown Los Angeles Criminal Courts building Robison said.

The 39 criminal counts filed Monday include the original allegations for which he was arrested in April.
